Non-Gaussianity in Nonminimally Coupled Scalar Field Theory
Seoktae Koh
We consider the non-Gaussianity of the nonlinear density perturbations in a single-field inflationary model when a scalar field couples nonminimally with gravity. Gravity theories…

Inflationary Solutions in Nonminimally Coupled Scalar Field Theory
Seoktae Koh, Sang Pyo Kim, Doo Jong Song
We study analytically and numerically the inflationary solutions for various type scalar potentials in the nonminimally coupled scalar field theory. The Hamilton-Jacobi equation is…

Nonlinear Evolutions and Non-Gaussianity in Generalized Gravity
Seoktae Koh, Sang Pyo Kim, Doo Jong Song
We use the Hamilton-Jacobi theory to study the nonlinear evolutions of inhomogeneous spacetimes during inflation in generalized gravity. We find the exact solutions to the lowest o…
